Optimization of catalytic wet peroxide oxidation of carbofuran by Ti-LaFeO3 dual photocatalyst

Catalytic Activity of Rare Earth Elements (REEs) in Advanced Oxidation Processes of Wastewater Pollutants: A Review

“…Fouad et al ( 2021) [76] tried to modify the LaFeO 3 catalyst with Ti (Ti-LaFeO 3 ) by developing photocatalysis and photo-Fenton processes under UV and visible light for the degradation of carbofuran (CBF). It was observed that about 20% of CBF was degraded by H 2 O 2 without catalyst loading under UV irradiation.…”

Atrazine degradation through a heterogeneous dual-effect process using Fe–TiO2-allophane catalysts under sunlight

“…The Bansal research group [ [17] , [18] , [19] ] first proposed the AOP process called the "dual-effect," which combines the advantages of the photo Fenton and photocatalysis processes. In this process, a synergetic effect has been reported by enhancing the degradation efficiency and reducing the time of photocatalytic reactions compared with both processes separately [ [19] , [20] , [21] ]. To perform a heterogeneous dual-effect process, it is necessary to use a solid catalyst with an active metal for the Fenton reaction (for example, Fe(II)/Fe(III) species) able to react with H 2 O 2 to generate the hydroxyl radical through a Fenton-like reaction [ 13 ].…”

“…Meanwhile, the solar spectrum typically contains about 4 % UV light; therefore, the sunlight cannot be efficiently used in the photocatalytic process [ 30 ]. To overcome this drawback, studies have shown that the doping of TiO 2 with other narrow bandgap materials, such as iron oxide, could reduce its bandgap and minimize e − /h + recombination rate [ 16 , 21 , 31 , 32 ]. In this way, it is possible to degrade emerging pollutants using photocatalysts containing both iron oxide and TiO 2 through a heterogeneous dual-effect process under sunlight.…”
